Default Lost right brake

We lost our right brake while turning on to the runway for takeoff. Spun around a couple of times and got it stopped. Saw fluid leaking out of failed brake. After the 1/2 mile walk/pull back to the apron we pulled the fairing and saw the puck fully extended. Got a ride back to home base from a friend and packed the car to fix the problem. Pads were extremely thin and I believe that coupled with the original brake rotors allowed the puck to extend past the seal.

Thinking we need to replace out brake rotors as well and am looking for suggestions of Rapco vs Cleveland. Price for the Cleveland is X2.

Thoughts ?

Rapco, near as I can tell.

Rapco is fine, you might also look into APS Black Steel, but I don't know the price point.

+1 Rapco. Of course I am just giving blind advice via the internet so take it for what you paid for it but unless there was a lot of metal scraping it is hard to imagine there was enough damage to need to replace the rotors.

Kevin,
Very, very glad you did not get airborne!
Recently lost a tire on landing and with full brake on the opposite side plus some crosswind help was able to keep it on the runway. Had to be towed back to hangar.
Suspect with one brake you would have had an interesting time on landing.

I change my pads at every CI. I fly almost 200 hours a year. Rarely have I used 1/2 the pads. I use the Matco reline service. $35. Cheap insurance. No desire to get stuck in the far off places I fly.

I had this happen on the RV7A when the pads got thin, and this was on relatively new rotors. It pays to replace the linings before they wear down that far. In my case I lost the left brake when pulling away from the gas pump and I thought I needed to use that brake to avoid hitting the pump. Fortunately I shut down fast enough that I avoided the collision but it was a very tense moment.

I have read reports here on VAF of brake pistons that were installed backwards, e.g., their O rings became exposed with only a relatively small extension. You might check yours.

I replaced worn Cleveland rotors with thicker Rapco rotors (RA164-09900). Better braking and less fade. Requires longer calliper bolts and a 1/8” shim for each calliper.

Default Rapco

I used Rapco works good last long time.
When reinstalling the brake pucks be sure they go back in like this. O-ring side goes in first.
